What is the significance of the nucleus in eukaryotic cells?

• It is responsible for energy production in the cell.

• It contains the cell's genetic material and controls its activities.

• It helps in the synthesis of proteins.

• It is involved in the detoxification of harmful substances.

What is the main difference between prokaryotic and eukaryotic cells?

• Prokaryotic cells have a nucleus, while eukaryotic cells do not.

• Prokaryotic cells are larger than eukaryotic cells.

• Prokaryotic cells do not have a nucleus, while eukaryotic cells do.

• Prokaryotic cells can perform photosynthesis, while eukaryotic cells cannot.

What is the primary function of the cytoplasm in a cell?

• To provide structural support to the cell

• To store genetic information

• To facilitate cellular processes and suspend organelles

• To control the movement of substances in and out of the cell

Which structure is not found in a prokaryotic cell?

• Nucleus

• Mitochondria

• Ribosomes

What is a cell wall?

• A flexible layer that allows movement in cells.

• A rigid outer layer that provides support and protection to some cells, such as plant cells.

• Unicellular organisms reproduce sexually, while multicellular organisms reproduce asexually.

• Unicellular organisms are always larger than multicellular organisms.

What type of organism is classified as autotrophic?

• An organism that produces its own food, like plants.

• An organism that consumes other organisms for food, like animals.

• An organism that decomposes organic material, like fungi.

• An organism that relies on external sources for energy, like some bacteria.

What is a defining feature of multicellular organisms?

• They are made up of more than one cell.

• They can reproduce asexually.

• They are always larger than unicellular organisms.

• They can live independently of other cells.
